SWEEPING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 480,231, dated August 2, 1892.

Application filed January 28, 1892. Serial No. 419,508. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES BRUSO, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Sweeping-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to sweeping-machines; and the object of my invention is to improve upon the construction and operation of automatic sweeping-machines as now ordinarily constructed and to provide an improved automatic sweeping-machine of simple construction and operation adapted to collect the sweepings and automatically discharge them into any suitable receptacle.

My improved sweeping-machine is made and operated independently of the receptacle into which the sweepings are automatically delivered and is adapted to be combined with any of the ordinary forms of two-wheel or fourwheel refuse-carts or street-carts.

My invention consists in my improved construction of the sweeping-machine and in adapting the same to be combined with any ordinary refuse-cart.

Referring to the drawings, Figure 1 is a side View of myilnproved sweeping-machine, looking in the direction of arrow at, Fig. 2. The rear part of the cart with which the sweeping-machine is combined is shown by dotted lines. Fig. 2 is a plan view of the sweepingmachine, looking in the direction of arrow b, Fig. 1; and Fig. 3 is a central vertical section of the sweeping-machine, taken on line 3 3, Fig. 2, looking in the direction of arrow to, same figure.

In the accompanying drawings a pair of wheels 1 1', which form the traction-surfaces and rest and turn on the ground or other surface over which the sweeper passes, are mounted on the axle 2, and upon said axle 2 is also mounted the rear part of the framework of the machine, upon which are supported the several parts of the machine. The framework of the sweeping-machine in this instance consists of the two side pieces or supports 4, connected by the cross-pieces 5, 6, and 7. The side pieces 4 of the frame are loosely mounted on the axle 2 at their rear end, and their front ends are provided with projecting arms 7', adapted to be connected with the rear end of the cart or receptacle with which the sweeping-machine is combined. In this instance the projecting ends 7 are provided with springs 8 and pins 9, which extend through the ends 7' and connect the same with the plate 10, attached to the rear part of the cart, as shown in Figs. 1 and 3.

The revolving'sweeper 11 extends between the wheels 1 and 1 and is supported in the lower ends of the arms 12, which are loosely supported at their upper ends on the axle 2. Curved arms 13 extend up from the lower ends of the arms 12 and are slotted at their upper ends and attached to the side supports a by means of set-screws 14: to allow of adj ustment of the sweeper in a vertical plane in the ordinary Way. The sweeper is operated in this instance by means of a pinion 15, faston one end of the shaft thereof and meshing with and driven by a gear-rim 16, secured upon the inner face of one of the wheels 1'.

Extending downwardly from the side supports 4 are the frames 17, consisting of the vertical arms 17 and 17 and the cross-piece 18. In the lower ends of the frame 17 are supported -three guiderolls It), 20, and 21, adapted to turn on said frame, and over the rolls 19 and 20 passes the endless apron 22, on which the sweepings swept up by the brush 11 are thrown and deposited. Upon one end of the shaft of the rolls 20 and 21 are secured in this instance sprocket-wheels 20' and 21.

Supported at the front ends of the side supports a of the frame of the machine and extending up therefrom are the stands 24:, in the upper ends of which are supported and adapted to revolve the guide-rolls 25, 26, and 27. Over the guide-rolls 25 and 26 extends the endless apron 22, and over the guide-roll 27 and the guide-roll 2i 011 the frame 17 extends the supplemental endless apron Said apron is adapted to travel over the outer surface of the apron 22 and to retain on said apron 22 the sweepings carried upon said apron. Upon the upper part of the stands 2st is secured the frame 29, extending out substantially at right angles therefrom and con- ICO sisting of the side supports 29 and 29". In the outer end of the frame 29, which is adapted to extend over the body 30 of the cart or other receptacle into which the sweepings are delivered, is supported the guide-roll 31, over which the endless apron 22 passes. In this instance a sprocket-wheel 32 is fast on one end of the shaft of the roll 31,and a sprocketwheel 33 and 34 is fast on one end of the rolls 25 and 26, respectively. A brush 35 is preferably secured on the upper ends of the stands 24 and adapted to brush off from the supplemental apron 28 any sweepings that may collect thereon onto the apron 22 to be delivered into the cart or other receptacle. A brush 36 is preferably secured to the front end of the frame 29 from the under side thereof, as shown in Fig. 3, to brush off any sweepings that may remain on the endless apron 22. The guide-rolls for the endless aprons are preferably driven by means of a chain 37, which passes over a sprocket-wheel 38, fast on the hub. of one of the wheels 1 and over the sprocket-wheels 23, 33, 32, 34, and 22 of the rolls 21, 26, 31, 25, and 20, respectively, as clearly shown in Fig. 1.

To the front ends of the frame of the machine are preferably secured the legs or sup ports 39, adapted to rest on the ground and support the front end of the machine when the same is detached from the cart or other receptacle.

A sheet-metal plate 40 is preferably attached to the lower end of the frame 17, and adapted to extend below the front portion of the sweeper 11, as shown in Figs. 1 and 3, to receive any of the sweepings from said wheel.

The operation of my sweeping-machine will be readily understood by those skilled in the art from the above description, in connection with the drawings, and is as follows: The front end of the frame of the sweeping-machine is attached to the cart or other receptacle into which the sweepings are to be automatically delivered by the machine, and said cart is then drawn by horse or hand power, or otherwise, causing the sweeping-machine to operate and the sweeping-roll 11 to revolve and deliver the sweepings onto the apron 22, which is continually moving over its guiderolls driven by the chain and sprocket-wheels, as above described, or otherwise, and carries the sweepings up and under the under surface of the supplemental endless apron 28, which is also continually revolving around its guide-rolls, and which supplemental apron 28 serves to retain the sweepings on the apron 22 when they are carried up in a substantially Vertical direction over the upper guide-roll 26. The sweepings remain on the apron 22 and are carried over the guide-roll 31 and discharged into the body of the cart or other receptacle, and anything remaining on the apron 22 is brushed 0% into the receptacle by means of the brush 26 or its equivalent. After the cart or other receptacle is filled with the swee in s the sweeping-machine is detached and 1 31a; immediately be attached to another cart or receptacle, thus avoiding any loss of time or delay while the first cart or receptacle is being discharged or dumped.

My sweeping-machine is especially designed to be used in street sweeping; but it may be also used in sweeping large or small areas under cover, automatically gathering the sweepings into a hand-cart, wheelbarrow, or other receptacle propelled by hand or otherwise.

The advantages of my improved sweeping machine will be appreciated by those skilled in the art. It is of very simple construction and operationand is not liable to get out of order, and may be combined with any ord dinary cart or other receptacle to automatically gather the sweepings and deliver them into said cart or receptacle.

The details of construction of the several parts of the sweeping-machine may be altered somewhat from what is shown and described, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
